The switch uses static domain name resolution to access host 10.1.1.2 through domain name 

host.com. 

Figure 1-2 Network diagram for static DNS configuration 

 

# Configure a mapping between host name host.com and IP address 10.1.1.2. 

<Sysname> system-view 

[Sysname] ip host host.com 10.1.1.2 

# Execute the ping host.com command to verify that the device can use static domain name resolution 

to get the IP address 10.1.1.2 corresponding to host.com. 

[Sysname] ping host.com

As shown in 

, the switch serving as a DNS client uses dynamic domain name resolution to 

access the host at 3.1.1.1/16 through its domain name host. The DNS server has the IP address 

2.1.1.2/16. The DNS suffix is com.
